MANUAL REACTOR SCRAM DUE TO FAILED OPEN TURBINE BYPASS VALVE

"At 1351 CST, the reactor was manually shutdown due to 'A' Turbine Bypass Valve opening. The Main Steam Line Isolation Valves were manually closed to facilitate reactor pressure control. Reactor level is being maintained through the use of Reactor Core Isolation Cooling System, Control Rod Drive System, and High Pressure Core Spray System. High Pressure Core Spray System was manually started to initially support reactor water level control. Reactor Pressure is being controlled through the use of the Safety Relief Valves and the Reactor Core Isolation Cooling System. The plant is stable in MODE 3.

"The cause of the 'A' Turbine Bypass Valve opening is under investigation at this time.

"The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - RADIOGRAPHY GUIDE TUBE KINKED WITH SOURCE EXPOSED

"Braun Intertec Corporation reported an event of the inability to retract a 1.44 TBq (39 Ci) Ir-192 sealed source (QSA Global, Inc. Model A424-9, SN 67476) which occurred at a temporary job site near Belfield, ND at approximately 4:02 pm CST on December 12, 2018. While performing radiography using a QSA Global, Inc. Model 880 Delta (SN D9541) exposure device on a pipe section resting on a stand, the pipe fell from the stand and kinked the guide tube. The radiography crew was unable to retract the source and immediately expanded the public dose boundary to an actual 2 mR/hr distance and maintained continuous surveillance and contacted their RSO for guidance. The RSO arrived on site the same day at approximately 8:45 pm CST and completed the source retrieval at approximately 9:45 pm CST. The sealed source was successfully retrieved into the exposure device. The maximum exposure readings from the direct reading exposure devices of the radiography crew and retrieval personnel was 3 mR. The crank assembly and guide tube were taken out of service. Visual inspection noted no defects to the pigtail assembly."
